Letters Patent No. 99,314, dated February 1, 1870.

IMPROVEMENT IN STREET-LAMPS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, J. F. EARLY, of KiptouStation, in the county of Lorain, and State of Ohio, have inventedcertain new and useful Improvements in Street- Lanterns; and I do herebydeclare that the following is a full and complete description of thesame, reference being, had to the accompanying drawings, making part ofthis specification.

Objective.

This invention relates to a street-lantern, constructed of twoconcavo-convex glasses, secured in metallicrims or bows hinged to eachother, which, on being closed, presents a flattened globe-like lantern.

A further improvement consists in so mounting the lantern on thelamp-postthat it may turn in the direction of the wind, therebypresenting to it oulya thin or narrow side, thus offering but littlesurface directly to the wind, and, therefore, is not liable to be blown-down during storms.

Drawings. Figure l is a front view of the lantern. Figure 2 is a sideview. Like letters of reference refer to like parts in the diflerentviews.

Description.

This lantern is constructed of two glass sides, B, fig. 2, each of whichis in shape a concavo-convex, similar to a. watch-crystal.

Said lasses are secured in rims or bows G D which are connected to eachother by a hinge, E, fig. 1, whereby one of the two sides may be openedto obtain access to the inside, but which, when closed, are fastened bythe lock F. v

At the lower side of the lantern is an G, for the admission of air tothe burner. Corresponding to the opening below, is anopening, H, at thetop, for the escape of the heated air and gas.

Said opening or vent is protected from the rain, 860., by a cap, I.

The globe or lantern is secured to the top of the air-passage,

made up of two pieces only, 7 use are made up of many pieces, held inplace by a post J, by means of the curved arms K, one section of thelantern being permanently attached to the upper part of the arms,through the intervention of the sleeve A, whereas the lower part of thearms are attached to the collar L, loosely fitted to the post, therebya1- lowing the lantern to rotate on the post and around the tube B ofthe burner.

The peculiar advantages resulting from a street-lantern constructed asabove described, are: More light fi'oma given sized burner will bethrown off, for the reason that the lantern has a larger amount of opensurface for the transmission of the light from the lamp or gas-jetwithin; the glass part of the lantern being whereas those in ordinaryframe, in e which the several pieces of 'glass are set, said frame, to agreat extent, obstructs the passage of the rays oflight, hence much ofthe light is lost. Also, the street-lanterns in ordinary use are of asquare form, thereby presenting a broad surface to the winds, whichcauses them not unfrequently to be blown down, which accident cannothappen t-oa lantern constructed 7 as above described, as the lanternwill "turn with the wind, thereby presenting its narrow side to it, andthus offer but little resistance 'to its force, and therefore escapebeing blown down. It is also much easier kept clean, as there are nocorners for the lodgment of dirt and dust, and therefore can-be keptclean and bright with less labor and expense.

What I claim as my improvement, anddesire to s'ecureby Letters Patent,is 1. A lantern, constructed of two concavo-convex sections, A B, in themanner substantially as descri ed,

and for the purpose set fortln 2. A lantern, constructed of the sectionsAB, provided with a cap, 'I, sleeve A, arms K, and collar L,

and arranged in. connection with the post J, so as to revolve thereon inthe manner as described, and for the purpose set forth.
